Review "...should be read by researchers who are interested in both historical and contemporary fertility trends." American Journal of Physical Anthropology "...will appeal to reproductive ecologists, demographic anthropologists, and particularly to demographers." Gillian R. Bentley, American Anthropologist Book Description Fertility in animals reflects access to scarce resources, such as food and territory. In humans the situation is more complex. In this book, the gap between socio-ecology and population demography is bridged, by showing how animals and humans adjust their fertility to environmental conditions.
